Analysis of Content (Pb) in Hair Tire Repair Shop Workers and Golden FishAlong The Soekarno-Hatta Bandar Lampung with Atomic Absorption Spectrophotometry. Lead is often referred to as a lead or of lead, the metal is denoted by Pb. Heavy metal lead can cause poisoning and accumulate in the human body. Process of entry into the body can lead through food and drink, the air and the penetration of the skin. Absorption through the skin may occur due to these compounds soluble in oils and fats. Lead through the air into the respiratory tract to be absorbed and binds to lung blood is then circulated to all the tissues and organs of the body, while by foods possible cause fish was foods source of protein had bepouled of lead. On the hair can be bound to sulfhydryl groups so that the lead content in the hair can be an Proses masuknya timbal ke dalam tubuh dapat melalui makanan dan minuman, udara, dan penetrasi pada kulit. Penyerapan lewat kulit ini dapat terjadi disebabkan karena senyawa ini dapat larut dalam minyak dan lemak. Timbal melalui udara masuk ke saluran pernafasan akan terserap dan berikatan dengan darah paru-paru kemudian diedarkan ke seluruh jaringan dan organ tubuh, sedangkan lewat maknan dapat terjadi karena makana khusunya ikan sebagai sumber protein telah terpapar timbal. Pada rambut timbal dapat terikat pada gugus sulfhidril sehingga kandungan timbal pada rambut dapat dijadikan indikator pencemaran timbal. Penelitian ini bertujuan untuk menganalisis kadar timbal pada rambut pekerja bengkel tambal ban dan ikan mas yang dipelihra di sepanjang jalan Soekarno-Hatta Bandar Lampung. Pemeriksaan dilakukan secara analisis kuantitatif menggunakan Spektrofotometri Serapan Atom. Pada penetapan konsentrasi timbal secara Spektrofotometri Serapan Atom diperoleh persamaan regresi linier larutan standar timbal yaitu y : 0,0100x-0,00933, koefisien korelasi (r x,y ) sebesar 0,999. Timbal memberikan serapan maksimum pada panjang gelombang 283,3 nm. Hasil penelitian menunjukan bahwa pekerja bengkel tambal ban positif telah tercemar timbal. Kadar timbal tertinggi yaitu 4,813 ppm sedangan kadar timbal terendah 0,258 ppm. Pada insang dan daging ikan kadar tertinggi 0,15878 dan 0,1160 ppm, kadar terendah 0,11636 dan 0,0539 ppm.
